Thanks Eagle. AdwCleaner and FRST run. Logs attached.

A “install.rdf could not be found” error popped up while FRST was running. Don’t know if that was related to FRST or coincidence. Only references I could find to it were related to Firefox. Error popped a second time but FRST continued on its way.

I noticed a 30-day file check in one of these and the prior set. This problem – or its evidence – has been around since I started using Avast in July.
